- Chroot installed on your machine.

## 2. Install MinIO in Chroot

```sh
mkdir -p /mnt/export/${USER}/bin
wget https://dl.min.io/server/minio/release/linux-amd64/minio -O /mnt/export/${USER}/bin/minio
chmod +x /mnt/export/${USER}/bin/minio
```

Bind your `proc` mount to the target chroot directory

```
sudo mount --bind /proc /mnt/export/${USER}/proc
```

## 3. Run Standalone MinIO in Chroot

### GNU/Linux

- For installations using Systemd MinIO service, upgrade via RPM/DEB packages **parallelly** on all servers or replace the binary lets say `/opt/bin/minio` on all nodes, apply executable permissions `chmod +x /opt/bin/minio` and process to perform `mc admin service restart alias/`.
